Rep. Alexandria Ocasio-Cortez (D-NY) suggested in a “60 Minutes” interview scheduled to air Sunday that the highest-earning Americans may need to pay an income tax rate as high as 60 to 70 percent to combat carbon emissions, reports Politico.

Speaking with Anderson Cooper in a “60 Minutes” interview scheduled to air Sunday, Ocasio-Cortez said a dramatic increase in taxes could support her “Green New Deal” goal of eliminating the use of fossil fuels within 12 years, a goal which even she acknowledges is ambitious.

“What is the problem with trying to push our technological capacities to the furthest extent possible?” Ocasio-Cortez asked. “There’s an element where yeah, people are going to have to start paying their fair share in taxes.”

Ocasio-Cortez pointed out that in a progressive tax rate system, not all income for a high earner is taxed at such a high rate. Rather, rates increase on each additional level of income, with dramatic increases on especially high earnings, such as $10 million. –Politico

Of course when France floated a 75% tax on the uber wealthy it resulted in a flood of high-profile departures, including French actor Gerard Depardieu who fled to Russia, while cratering the country’s real estate market and ultimately leading to the plunge in Francois Hollande’s approval rating.
